Grammacephalus Haupt

Remarks. For recent treatments of this genus see Linnavuori (1978) for Africa and Viraktamath (1981) and Viraktamath & Murthy (1999) for India. Also, Dlabola (1982) described two species from Iran and Dai et al (2006) described a new species from China. A world check-list of the genus was also given in the latter work but the two Dlabola species, G. minabicus and G. genoicus , were omitted.

Grammacephalus genoicus Dlabola (Plate 2, g; Fig. 22 ).

Material examined. Pakistan: 13, Tando Jam.

Remarks. The species, previously known only from Iran differs from all other species for which males are known in lacking pygofer processes and having a short tenth segment of the anal tube.

Grammacephalus indicus Viraktamath & Murthy (Plate 2, h; Figs 20–21 )

Material examined. Pakistan: 23, 1Ƥ Tando Jam, 28.iv.08, A. Behan, sugar cane; 13, Nawabshah, 12.v.1971. Remarks. The male genitalia of the material examined matches the original figures of G. indicus but the vertex is shorter with slightly different markings.

Grammacephalus pallidus Linnavuori (Plate 2, i; Fig. 23 )

Material examined. Pakistan: 13, Rawal Dam, ix.1985, C. & L. O’Brien.

Remarks. Externally and in the male genitalia the above material matches the original figures of G. pallidus , previously known only from Sudan. The vertex markings are also similar to G. genoicus and G. minabicus Dlabola (1984) (male unknown) but the female pregenital segment is different in shape. The shape of the aedeagus in G. pallidus is similar to G. acuticeps Linnavuori (1978) and G. furcatus Dai & Zhang (in Dai et al, 2006) but there are some differences in this and other genitalic structures.
